For some unreliable database types. The man page clearly states it is
100% reliable for back-bdb and back-hdb (the back-null is not a real
database).

Lookingh at your configuration, I note "dnbosync" which means looking for
trouble. Also, you placed your data in "/mnt/storage/wifi"; does it
indicate some remote storage? That's also looking for trouble. Please
don't complain about software reliability when you violate the essential
rules of reliability: know what you're doing, and one unreliable point in
the chain makes the whole chain unreliable.
This seems to all end up in not having checked the documentation carefully
enough, and in having misused some unreliable options. So I strongly
recommend you stop posting to openldap-bugs, and start posting to
openldap-software (after you re-read the relevant documentation, of
course).
